The Boeing 777 vs 787 – What Plane Is Better?


The Boeing 787 Dreamliner has been a revolutionary aircraft. It has allowed super cheap long haul carriers to exist and insanely long routes to open.

But few remember which aircrafts thunder the 787 stole: The Boeing 777 family had long been the workhorse of the airline industry, and before the arrival of the Dreamliner it was thought to have its future guaranteed.

Now with the 787 able to easily perform many of the routes the 777 was designed for, many airlines have either upgraded or simply resigned to await the 777X’s arrival later this year. But was it too soon? Is the Boeing 787 actually better than the Boeing 777? Let’s find out.

Naturally, the 787 was not initially designed to be a competitor to the 777. It would be crazy for Boeing to design a new plane that would compete with its own aircraft, but we can look at the comparison from an airline point of view to see which is best and most cost effective.

Boeing 777 vs Boeing 787

A great way to understand how these two families of aircraft compare, is to begin with a top-down look. Below is a table of the aircraft, ranked by how many passengers they carry configured in two classes.

Type Length Span Passengers (2-class) Passengers (Max) Range List price
787-8 56.69 m 60.17 m 242 356 7,355 nm US$239.0M
787-9 63 m 60.17 m 290 406 7,635 nm US$281.6M
777-200 63.73 m 60.93 m 313 440 5,240 nmi US$261.5 M
777-200ER 63.73 m 60.93 m 313 440 7,065 nmi US$306.6M
777-200LR 63.73 m 64.80 m 317 440 8,555 nmi US$346.9M
787-10 68.27 m 60.17 m 330 440 6,430 nm US$325.8M
777-300 73.86 60.93 m 396 550 6,030 nmi US$361.5M
777-300ER 73.86 64.80 m 396 550 7,370 nmi US$375.5M

As we can see above, the two smaller 787’s only beat out the 777s in terms of range. However, the 787-10 comes into its own against the 777 family, and will be the main aircraft we will be comparing.



The Boeing 777 series is a bigger plane than the 787 and thus is able to carry more passengers. The 787-10 is actually more effective than the 777-200 series but is beaten by the 777-300 by around 66 passengers. This is a significant number and can’t be argued.

This is a bit more complicated. The 787 beats the 777-300 in range, but the smaller, lighter 777-200s and special extended-range versions of the 777 (777-300ER and 777-200LR) can fly circles around the Dreamliner.


Winner: 777

List Price

But is the better passenger capacity and range worth an extra $50 million dollars (787-10 vs 777-300ER)? It seems that the 787 is cheaper to deploy than nearly every variant of the 777. Will those extra passengers actually translate into at least $50 million dollars worth of revenue over the lifetime of the aircraft?

That’s a risk many airlines will not want to take. We should also take a second to point out that many airlines don’t actually pay list price, but around 50%.

Fuel Efficiency

There is an area that we have yet to touch on, and that is fuel efficiency. The 777 series is far older than the 787 and uses construction materials that are heavier. This means that a 787 can not only fly further on less fuel, but is far more efficient on the same routes.

Looking at the above graph we can see that the Boeing 787-9 is incredibly fuel efficient when compared to any of the 777 series. It is without a doubt that the same can be said for the 787-10.

Winner: 787

At first it looks like the 777 is a slam dunk, but when the 787 is cheaper to buy and operate it slowly becomes a much easier financial decision. This VS article did not take into account issues with the engines on the 787, nor the improved flight experience for passengers on the new plane. An airline with the new 787 would be able to outperform an older 777 fleet any day of the week if it was down to customer comforts.

What about the Boeing 777x vs the Dreamliner?
